pecication of Letters Patent.

or the lUnited States, residing,y in the city of -lthiladelphim county of Philadelphia, and

State of Pennsylvania, have invented a new and useful lnipiioveinent in Hogncraping 1s a specii treaties.

My invent-ion is a scia-pingA machine des signed :tor de-hairing hogs rapidly, con-- veniently and. effectively.

A leading object of the invention 1s to provide means by which carcasses can be carried in successionv along constantly moving scrapers and simultaneously adjusted to the desired positions, being turned automatically sc as to present the ditterent part-s ot the body to the Scrapers.

tion are fiily disclosed in I.the following description and the accompanying drawings 1n illustration thereof.' f

21, forming a ln the drawings, Figure l is a plan view of mechanism embodying improvements of my invention, parts being broken away to illustrate features of the construction; Fig. 2 is a sectional elevation oit' the scraping mechanism proper; Fig; 3 .is a perspective view of a section oi sprocket chain or link belt with a scraper attached thereto; and

fr is a sectional end elevation ot the ina-- chine.

The apparatus illustrated in the drawings comprises a trame consisting of the posts l, the connecting. beams 2 and 3, and a sill 4 supported by the beams A bed is formed by the cross beams .3, the parallel sills 6 sup.- ported by and lined to the beams, the parallel angles 7' supported on and fixed to the sills, the parallel angles 8 disposed. beneath the sills, and the tie plates 9 which connect the langles 8 with the previously described bed members. The beams are pivotally connected, by pintles 10with the bearings 1l on the sill 4, and the bed is adjusted to thedesired inclination by racks l2 fired thereto and pinions 13 engaging-the racks, the pinicns being fixed on a shaft le turned by a handle l5 thereon in thelbearings 16. Shafts 17 are journaled in thebearings 18 carried by the sills 6, sprocket wheels i9 are hired on these shafts, sprocket chains or link belts 20 are carried by the wheels, and slats exible floor ct a moving plattform, are carried bythe chains.` A beveled thron gli vmoves on its fulcrnm.

Gear 22. is finie-d to one of the shafts l? and is riveli, to move the flexible licor, by an engaging beveled pinion 23 on the shaft 24. jonrnaled in the bearings 25, the beveled gears retaining their engagement throughout the movement of the bed on t'ulcrnins. A sprocket wheel 26 is tired on the shaft 24 is engaged by a sprocket chain 2'? with a sprocketwheel Q8 tired on a shaft 29, the latter being journaled in bea-rings SO' carried by nprights l and revolver` 'by a pulley hired to it, whereby the'platt'orni is moved the intermediate mechanism described. Sprocket wheels 32ans tired at intervals on the shai't 29, and sprocket Wheels 33 are fixed at intervals cna shaft 5134i which is journaled in bearings on the uprights i which carry the beariiws 3l). Link belts 36 The characteristicl features oi the invenpassover and are carriiid by their respective pairs el? sprocket wheels 32 and 33, linlrsof the respective belts having fixed thereto the flexible sheet metal Scrapers 3'?.

The links which carry the Scrapers have the laterally projecting bearing members 38 thereon to which the Scrapers 37 are con' nected by bolts 39 and 40, the bolts having` suiiicient play to permit the Scrapers a limited movement on their bearings as a lever The bolts fi() are extended a snilicient distance beyond their respective bearings to permit the interposif tion ci2 springs 41 between the bearings and the nuts of the bolts, by which they are engaged, the springs being adjustable in ten sion by` adjusting the nuts, whereby iiexibility is provided to permit the Scrapers to operate to adapt the action to the work and prevent straining the resistance in the path thereof.

In operation, t-he pulley 3l is revolved in the' direction of the arrow thereon, the floor 21 is movedv in the direct-ion of its arrow, and the carcasses placed in succession on the floor are carried transversely. to the Scrapers which move upwardly in Contact therewith. The bed is given such inclination that the carcasses are so placed in relation to the Scrapers that they will tend to move' into the path thereolr` and will be turned thereby to permit the Scrapers to engage and scrape the entire body.
